Pew's findings show that electronic device adoption in the US - specifically tablets and smartphones - tend to increase in younger and more affluent demographics. Further, against the stereotype that older age groups tend to be technophobes, there is a growth in tech adoption across age groups.
E-book adoption, in contrast, goes against these trends. Kobo, for example, in reference to "data from its own customers as well as a survey of 16,000 readers using Kobo e-readers and competing device", state that 77% of the most active users are 45 and over, with the largest single group aged between 55 - 64. Further, there is a decline in both e-book and e-reader sales, with data showing that younger readers prefer the paper format over e-books.
